longitudinal groove ; clypeus not separated from the face, punc- 

 tured like the head ; antennae black, the lower three joints 

 fulvous, second joint as long as the third, terminal joints thick- 

 ened ; thorax about one-half broader than long, the sides strongly 

 rounded and deflexed anteriorly, the surface raore finely and 

 irregularly punctured than the head, the sides nearly impunctate ; 

 elytia with deep and strong rows of punctures, the interstices at 

 the sides longitudinally convex ; underside metallic green, im- 

 punctate ; femora with a small tooth, the knees, tibiae, and the 

 tarsi fulvous, the last partly stained with piceous. 



Hah. Zambesi (my collection). 



Of this species I possess three specimens, one of which is pro- 

 bably a male ; in this sex the clypeus is feebly separated from the 

 face, more closely punctured and broader and the femoral teeth 

 are more pronounced, otherwise there is no difference of im- 

 portance. I cannot identify the insect with 8. ruHpes Weise 

 (Deutsche ent. Zeit. 1883, p. 355), since the author describes his 

 species as " short and ovate " and the thorax as strongly punc- 

 tured ; it belongs probably to Menvus Chap. S. viinutv,s Jac, is 

 much smaller and has a strongly rugosely punctured thorax. 



Syagrus tristis, sp. n. 



Elongate, subcylindrical, piceous ; head closely rugose-punctate ; 

 thorax opaque, densely punctured, the sides finely serrate ; elytra 

 deeply punctate - striate, the interstices at the sides strongly 

 costate ; femora strongly dentate. 



Length 4 millim. 



Head strongly rugose throughout, the vertex strigose, opaque, 

 eyes surrounded by a very nari-ow sulcus ; antennas piceous or 

 dark fulvous, rather long and robust, the second joint distinctly 

 shoi-ter than the third ; thorax one-half broader than long, 

 moderately convex, slightly narrowed at the base, the lateral 

 margins feebly rounded and finely serrate, the surface crowded 

 with shallow round punctures, opaque, of leathery appearance ; 

 scutellum sxibpentagonal, smooth ; elytra stibcylindrical, wider at 

 the base than the thorax, slightly depressed below the base, 

 piceous or nearly black, shining, very deeply and closely punctate- 

 striate, the punctures mostly transverse in shape, the interstices 

 at the sides strongly longitudinally costate ; underside piceous, 

 impunctate ; legs robust, femora strongly dentate ; prosternum 

 longer than broad, strongly rugose.

"Whether this species is distinct or not from ;S'. opaca Jac. is 

 somewhat doubtful ; at any rate it is very closely allied ; but the 

 thorax in S. tristis is more closely and strongly punctured, and 

 the same is the case with the elytra, which in >6'. opaca have the 

 punctures shallow and nearly obliterated towards the apex ; in 

 the present species they are more shining, the punctures are 

 deep and large and scarcely finer posteriorly ; but these seem to 

 be the only difi'erences. Of each species I have three and four
